Give your body the afternoon to adjust while you&#8217;re still awake.\n    <\/div>\n\n    <!-- REMEDIES SECTION -->\n    <h2 id=\"remedios\">\ud83d\udc8a Altitude sickness remedies that actually work in Cusco<\/h2>\n\n    <p>Here is what travelers who arrive with Turismo Liberty use \u2014 and what the science actually supports:<\/p>\n\n    <ul class=\"steps\">\n      <li><strong>Coca tea (mate de coca):<\/strong> The most traditional and effective remedy. Available free at most hotels; also sold at the San Pedro Market. It helps vasodilate blood vessels and reduces mild headache and fatigue. Not a cure, but it genuinely helps during the first 24 hours at elevation.<\/li>\n      <li><strong>Hydration \u2014 2 to 3 liters per day:<\/strong> Altitude causes faster dehydration. The body loses more water through breathing at lower barometric pressure. Water, herbal teas, and soups are your best allies. Avoid coffee and alcohol the first two days.<\/li>\n      <li><strong>Sorojchi Pills:<\/strong> An over-the-counter analgesic sold in Cusco pharmacies (approx. S\/5). Relieves mild headache and nausea once symptoms appear. It does not prevent AMS \u2014 it manages existing symptoms while your body acclimatizes.<\/li>\n      <li><strong>Acetazolamide (Diamox):<\/strong> The only pharmacological prevention backed by solid evidence. Prescribed by a doctor before departure (typically 125\u2013250 mg twice daily). Consult your physician at least a week before travel if you plan to use it.<\/li>\n      <li><strong>Supplemental oxygen:<\/strong> Available at some hotels and clinics in Cusco. Turismo Liberty guides carry portable oxygen on high-altitude excursions like Rainbow Mountain (5,200 m). A short oxygen session provides fast relief for moderate symptoms.<\/li>\n    <\/ul>\n\n    <!-- WHAT TO DO \/ NOT DO -->\n    <h2 id=\"comparativa\">\u2696\ufe0f What to do and what NOT to do on your first day in Cusco<\/h2>\n\n    <table>\n      <thead><tr><th>\u2705 DO<\/th><th>\u274c DO NOT<\/th><\/tr><\/thead>\n      <tbody>\n        <tr><td>Drink coca tea from the moment you arrive<\/td><td>Drink alcohol (beer, wine, spirits) for the first 48 hours<\/td><\/tr>\n        <tr><td>Drink 2\u20133 liters of water throughout the day<\/td><td>Eat heavy meals, fried food, or large portions of red meat<\/td><\/tr>\n        <tr><td>Rest horizontally for 30\u201345 min after arriving<\/td><td>Rainbow Mountain (5,200 m) \u2014 only from day 3\u20134 at the earliest<\/td><\/tr>\n        <tr><td>Eat light: soups, quinoa, fruit<\/td><td>Take a very hot shower (lowers blood pressure)<\/td><\/tr>\n        <tr><td>Take Sorojchi Pills if you get a headache<\/td><td>Attempt Machu Picchu on day one \u2014 even at 2,430 m, the journey is long and exhausting<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n\n    <p>A common question from US and European travelers is whether going to the <strong>Sacred Valley of the Incas<\/strong> on day one is a smart strategy.

The body begins producing more red blood cells to compensate for lower oxygen. The key is to avoid intense physical activity on day one, drink 2\u20133 liters of water, skip alcohol, and take coca tea from arrival onward. Full acclimatization to higher elevations like Rainbow Mountain (5,200 m) takes 3\u20134 days.<\/p><\/div>\n    <\/div>\n\n    <div class=\"faq-item\">\n      <div class=\"faq-question\">What are normal altitude sickness symptoms vs. warning signs?<\/div>\n      <div class=\"faq-answer\"><p>Normal in the first hours: mild headache, fatigue, slight dizziness, and mild shortness of breath when walking fast. Warning signs that require medical attention: difficulty breathing at rest, confusion or disorientation, coughing with foamy liquid, persistent vomiting, and chest pressure. In those cases, seek medical help or descend to a lower elevation immediately.<\/p><\/div>\n    <\/div>\n\n    <div class=\"faq-item\">\n      <div class=\"faq-question\">What tours can I do on the first day in Cusco?<\/div>\n      <div class=\"faq-answer\"><p>Day one should be reserved for gentle acclimatization. Turismo Liberty recommends the Cusco city tour (Qorikancha, Sacsayhuam\u00e1n, Tambomachay) as the ideal first-day activity \u2014 it&#8217;s moderate, done by vehicle, and lets you see the city at a relaxed pace. Demanding hikes like <a href=\"https:\/\/turismoliberty.pe\/en\/trip\/humantay-lagoon-tour-discover-cuscos-natural-paradise\/\" target=\"_blank\">Humantay Lake<\/a> (4,200 m) or Rainbow Mountain Vinicunca (5,200 m) should be saved for day three or four minimum.<\/p><\/div>\n    <\/div>\n\n    <div class=\"faq-item\">\n      <div class=\"faq-question\">Is the Sacred Valley a good first stop to avoid altitude sickness?<\/div>\n      <div class=\"faq-answer\"><p>Yes, it&#8217;s an excellent strategy. The Sacred Valley of the Incas sits between 2,600 and 2,900 m \u2014 significantly below Cusco&#8217;s 3,399 m. Spending the first night in Ollantaytambo or Urubamba before heading up to Cusco on day two considerably reduces AMS risk. Turismo Liberty can arrange this order within the Cusco package \u2014 just ask us via WhatsApp.<\/p><\/div>\n    <\/div>\n\n    <div class=\"faq-item\">\n      <div class=\"faq-question\">Do Sorojchi Pills work for altitude sickness?<\/div>\n      <div class=\"faq-answer\"><p>Sorojchi Pills are an over-the-counter analgesic sold at Cusco pharmacies (approx. S\/5) that relieves mild altitude sickness symptoms like headache and nausea. They do not prevent AMS \u2014 they act on symptoms once they appear. For pharmacological prevention, a doctor may prescribe Acetazolamide (Diamox), which is taken before arrival. Always consult your physician before travel if you have pre-existing health conditions.<\/p><\/div>\n    <\/div>\n\n    <div class=\"faq-item\">\n      <div class=\"faq-question\">When can I do Rainbow Mountain or Humantay Lake?<\/div>\n      <div class=\"faq-answer\"><p><a href=\"https:\/\/turismoliberty.pe\/en\/trip\/humantay-lagoon-tour-discover-cuscos-natural-paradise\/\" target=\"_blank\">Humantay Lake<\/a> sits at 4,200 m and Rainbow Mountain Vinicunca at 5,200 m. Turismo Liberty recommends not attempting either before your third or fourth day in Cusco. If you&#8217;re coming directly from sea level, wait at least 48 hours before any high-altitude hike. The 4-day Cusco package from Turismo Liberty already has this sequence built in.<\/p><\/div>\n    <\/div>\n\n    <!-- BANNER 5 -->\n    <div class=\"banner-wrap\">\n      <div class=\"banner-azul\">\n        <div class=\"banner-azul-icon\">\u26a1<\/div>\n        <div class=\"banner-azul-body\">\n          <div class=\"banner-azul-title\">Questions about your fitness level for Cusco tours?
